TE Connectivity HTU21 Temperature & Humidity Sensor Add On Board Digilent Pmod

The HTU21D peripheral module provides the necessary hardware to interface the HTU21D digital relative humidity and temperature sensor to any system that utilizes Pmod compatible expansion ports configurable for I2C communication. The HTU21D sensor is a selfcontained humidity and temperature sensor that is fully calibrated during manufacture. The sensor can operate from 1.5V to 3.6V, has selectable resolution, low battery detect, and checksum capability. The HTU21D has a low power standby mode for power sensitive applications.
